Smith-Blair Style 325 Bronze Service Saddle - PVC at Steel or DI OD, 4-12 in

The Smith-Blair Style 325 is a bronze service saddle for tapping branch connections on PVC water mains. The cast red brass body resists corrosion, wraps the pipe for nearly 360° of support and reinforcement, and is held by a single 3.5 in wide Type 304 stainless steel strap on four studs for a wide, stable stance.

This listing carries the OD-specific bodies, each cast for one PVC pipe OD — steel (IPS) OD or cast/ductile iron (C900) OD — in 4, 6, 8, 10 and 12 in, with 3/4 to 2 in NPT or CC outlets. It also serves for air/vacuum valves, drain valves and other service equipment.

Application: service taps of 3/4 to 2 in on 4-12 in PVC pipe, sized to steel or ductile iron OD.

Key Features

• Working pressure up to 150 PSI, depending on size and application
• Cast red brass body for corrosion resistance
• OD-specific bodies give nearly 360° support and reinforcement on PVC
• Single 3.5 in wide 304 stainless strap on four studs for a wide stance
• Meets applicable AWWA C800; certified to NSF/ANSI 61

Up to 150 PSI. depending on size and application. Smith-Blair notes the allowable pressure depends on pipe size, type of pipe, service conditions and installation workmanship.

PVC with steel (IPS) or cast/ductile iron (C900) OD, matched to the body OD. For rigid steel, ductile iron or cast iron pipe, the Style 325 rigid-pipe bodies (OD range) are listed separately.

Choose the size and pipe OD in the first option and the tap in the second; the part number shows in the last option.

• Confirm the saddle type, tap size and pipe OD range match the job, then clean the pipe where the gasket will seat, removing scale, dirt and debris.
• Check the gasket is seated in the body; lubricate the pipe and gasket with a soap-and-water solution (anti-freeze may be required) that meets the water and pipe supplier's requirements.
• Mount the body as close to the final tap position as possible and check its location before tightening: moving or rolling the body on the pipe can damage the gasket.
• Tighten the 5/8 in nuts progressively and evenly to the torque in the instructions, keeping the stud lengths on both sides equal; do not over-torque. The saddle seals the tap and is not designed to give structural rigidity to connections or equipment, so support those separately.
• Make the connection with a pipe-thread compound that both lubricates and seals (no tape products), without cross-threading or rocking the saddle body.
• Pressure-test the saddle for leaks before making the tap.
